Gateway Contracts Move to Versioned Capability Flags

The previous endpoint model encoded feature availability directly in route versioning, which made controlled rollout expensive. The new contract keeps stable routes while capability flags gate preview behavior at the schema layer.

Version numbers remain stable while behavior evolves behind explicit flags

Migration Path

Introduce negotiated headers, deprecate route forks, and expose capability manifests in generated SDK metadata.
